Introduction

AI Translation

TPS5402是一款具有宽运行输入电压范围（3.5V至28V）的单片非同步降压稳压器。此器件执行内部斜坡补偿的电流模式控制来减少组件数量。 TPS5402还特有一个轻负载脉冲跳跃模式，此特性可在轻负载时减少为系统供电的输入电源的功率损失。 可使用一个外部电阻器将此转换器的开关频率设定在50kHz至1.1MHz之间。引入了频率展频操作以减少EMI。 具有频率折返功能的逐周期电流限制在过载情况下保护集成电路(IC)。

The TPS5402 is a monolithic non-synchronous step-down regulator with a wide input voltage range (3.5V to 28V). The device implements current mode control with internal slope compensation to reduce component count. The TPS5402 also features a light-load pulse skipping mode, which reduces power loss from the input supply powering the system under light load conditions. The converter's switching frequency can be set between 50kHz and 1.1MHz using a single external resistor. Frequency spread spectrum operation is incorporated to reduce EMI. Cycle-by-cycle current limiting with frequency foldback protects the IC under overload conditions.
